我使用安装 Postgresql
sudo apt install postgresql postgresql-contrib
然后我跑
sudo systemctl restart postgresql
然后我跑
sudo systemctl status postgresql
它说
Active: active (exited) since ... 1s ago
因此看起来重启命令立即退出。
说/var/log/postgresql/postgresql-12-main.log：

我如何解决它？
附言：我遇到的问题是 Postgresql不会开始.restart执行命令后其状态应为 ，active (running)而 则为active (exited)。
我尝试清除 postgresql 并运行
sudo apt-get install postgresql
再次，这是 /var/log/postgresql/postgresql-12-main.log：
